What is the velocity of the box at 1.20 : A boy is attempting to swim directly across a river; he is able to swim at a speed of 0.421 m/s relative to the water. The river is 2.48 m wide and the boy ends up at 4.77 m downstream from his starting point.

The force on the mass exerted by the spring : A 30 gram mass is hanging from a spring whose unstretched length is 20 cm and whose spring constant is 2.5 N/m. In the list below are described 5 situations. In some of the situations, mass is at rest and remains at rest. In other situations, at the ..

Calculate the speed of the fetal heart : A piece of wood is 6.00 m long, 0.260 m wide and 0.060 m thick. Its density is 600kg/m cubed. What volume of iron ( P iron = 7.8 x 10 cubed kg/m cubed) must be fastened underneath the wood to sink it so that the top surface of the wood is just even w..

Suppose that charges can be represented as point charges : A driver in a car travelling at a speed of 58.0 mi/h sees a deer 126 m away on the road. Calculate the minimum constant acceleration that is necessary for the car to stop without hitting the deer (assume that the deer does not move in the meantime).
